山東省青(qing)州市魯東機械2.1MW光伏(fu)發(fa)電(dian)(dian)站(zhan)項目。彩(cai)鋼瓦屋(wu)頂光伏(fu)發(fa)電(dian)(dian)站(zhan)，已并網發(fa)電(dian)(dian)成(cheng)功(gong)！

輸送方式

太陽能光(guang)(guang)伏發電(dian)(dian)分為獨立光(guang)(guang)伏發電(dian)(dian)、并網光(guang)(guang)伏發電(dian)(dian)、分布式光(guang)(guang)伏發電(dian)(dian)

獨立光伏發電

獨立光伏發(fa)電(dian)(dian)系統(tong)也(ye)叫離網光伏發(fa)電(dian)(dian)系統(tong)。主要由太(tai)陽能電(dian)(dian)池組件、控制器、蓄電(dian)(dian)池組成，若(ruo)要為交流負載供電(dian)(dian)，還需要配置(zhi)交流逆變(bian)器。

并網光伏發電

并(bing)網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)系統就是(shi)太陽(yang)能組件產生的直(zhi)流電(dian)經(jing)過并(bing)網(wang)(wang)(wang)逆變器轉換成符(fu)合市(shi)電(dian)電(dian)網(wang)(wang)(wang)要求的交(jiao)流電(dian)之后直(zhi)接接入(ru)公共電(dian)網(wang)(wang)(wang)。并(bing)網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)系統有集中式大型并(bing)網(wang)(wang)(wang)光(guang)伏(fu)電(dian)站一(yi)般(ban)都是(shi)國家級電(dian)站，主(zhu)(zhu)要特點(dian)是(shi)將(jiang)所發(fa)(fa)電(dian)能直(zhi)接輸送到電(dian)網(wang)(wang)(wang)，由電(dian)網(wang)(wang)(wang)統一(yi)調配向用戶供電(dian)。但這種電(dian)站投(tou)資大、建設周期長(chang)、占地(di)面(mian)積大，發(fa)(fa)展難度相對較大。而(er)分散式小(xiao)型并(bing)網(wang)(wang)(wang)光(guang)伏(fu)系統，特別是(shi)光(guang)伏(fu)建筑一(yi)體(ti)化發(fa)(fa)電(dian)系統，由于投(tou)資小(xiao)、建設快、占地(di)面(mian)積小(xiao)、政策支(zhi)持力(li)度大等優點(dian)，是(shi)并(bing)網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)的主(zhu)(zhu)流。

分布式光伏發電

分(fen)布(bu)式(shi)光伏發電(dian)(dian)(dian)(dian)系統，又稱分(fen)散式(shi)發電(dian)(dian)(dian)(dian)或(huo)分(fen)布(bu)式(shi)供能，是指在用戶(hu)現(xian)(xian)場(chang)或(huo)靠近用電(dian)(dian)(dian)(dian)現(xian)(xian)場(chang)配置(zhi)較小的光伏發電(dian)(dian)(dian)(dian)供電(dian)(dian)(dian)(dian)系統，以滿(man)足特定用戶(hu)的需(xu)求，支(zhi)持現(xian)(xian)存配電(dian)(dian)(dian)(dian)網的經濟(ji)運行，或(huo)者(zhe)同時滿(man)足這兩個方面的要求。

　　分布式(shi)光伏(fu)發電(dian)(dian)系統(tong)的(de)基本設(she)備(bei)包括光伏(fu)電(dian)(dian)池(chi)組(zu)件(jian)、光伏(fu)方陣(zhen)支架、直(zhi)流(liu)匯流(liu)箱、直(zhi)流(liu)配電(dian)(dian)柜、并(bing)網逆(ni)變器(qi)、交流(liu)配電(dian)(dian)柜等設(she)備(bei)，另外還有供電(dian)(dian)系統(tong)監控裝置和(he)環境監測裝置。其運行模式(shi)是在有太(tai)陽輻射的(de)條件(jian)下，光伏(fu)發電(dian)(dian)系統(tong)的(de)太(tai)陽能(neng)電(dian)(dian)池(chi)組(zu)件(jian)陣(zhen)列將太(tai)陽能(neng)轉換輸(shu)出的(de)電(dian)(dian)能(neng)，經過(guo)直(zhi)流(liu)匯流(liu)箱集中送入直(zhi)流(liu)配電(dian)(dian)柜，由并(bing)網逆(ni)變器(qi)逆(ni)變成交流(liu)電(dian)(dian)供給建(jian)筑自身負載，多余或(huo)不足的(de)電(dian)(dian)力通(tong)過(guo)聯接電(dian)(dian)網來(lai)調節。
